Fig. 12 is a front elevational view of a further modification of the invention with parts broken away and parts shown in section,

Fig. 13 is a schematic view illustrating the invention mounted for raising and lowering a window on a vehicle door.

In the drawings as shown in Fig. 13 we have illustrated the invention used in connection with a vehicledoor 25 having a window 26 which is adapted to slide vertically, and which is provided at its lower edge with a rim 21, the end edges -.-..1?1s.- 1131s :.a. front -el rational (View of; af i th of the window 26 sliding in guides 28 and 29. The upper end of a bar 30-is pivotally connected to the strip 21 and, at its lower end, this bar 30 is connected pivotally to one end of a segment arm 3| which is positioned in a recess 32 formed in the door 25 and closed by a cover plate 33.

As shown in Fig. 1 this segment arm 34 is provided at its opposite ends with a head 35 provided with teeth 36 on its periphery. As shown in Fig. 3, this head 35 is mounted for rotation on the axle 31 which projects through the bushing 38, this bushing 38 being fixedly mounted on the supporting plate 39, and the shaft 3'! being held in position by a split ring 31a. This plate 39 has an opening formed therethrough, through which extends the reduced knurled portion 4| of the shaft 40, the end of the shaft being upset as at 42 to securely mount the plate 39 on the shaft 40. A key 43 serves to connect the shaft and the sleeve 44 for rotation in unison with each other. In, the invention is used a vane or blade B which is shown in the drawings as being formed from a'single sheet of light metal having the portion 45 which embraces the sleeve 44 and which is turned outwardly radially therefrom .to provide the pair of plates 46 and 41. As shown in Fig. 5 the plate 41 is provided with a flange 48 spaced apart from a flange 49 formed on the plate 46 to provide a channel along the side edges of one side. Similar flanges 50 and 5| are formed on the plates 41 and 46 at the other side to provide a channel. The end portions of these plates 46 and 41 are provided with the flanges 53 and 52 which cooperate to form a channel at the end edge of the blade or vane B. Mounted in these channels is an endless flexible sealing strip 54 which also passes around the sleeve 44 at opposite ends, this sleeve 44 being cut away as at 45 at its opposite ends to provide a groove for reception of the sealing strip. v In the invention is employed a hollow housing or drum comprising a pair of sections 55 and 56 each of which is formed cup-shaped and pror d s at. i s, 99 3. nd w h wee iwer lt re jecting flanges 51 and 58 which are secured toi gether by the rivet 59, a layer 60 of sealing material being clamped between these flanges 51 and 58. A central opening is provided in the bottom of each of these cup-shaped sections and at these central openings an inward-ly turned sleeve BI is viofmed to project into the cut away section 60 formed in the sleeve 44 so that a housing is thus rotatively mounted relatively to the sleeve 44 and in operation this housing rotates about the axis of the shaft 40. A plate -62 is secured to one of the faces of the housing and spaced from this plate is another plate "201. Positioned between these plates 62 and 62a is a gear 64 which meshes with the teeth onthe head 35. Rivets 63 are projected through the plates 62 and 62a as well as the gear 64 to provide a unitary assembly. V

Rotatively' mounted "on the shaft Mi a ether" 65 projecting outwardly from one side or which is a tube 66 having a ipassage'alfl formed therethrough. Projecting outwardly from this sonar 65 which is shown inFig. 3 man arm clearly shown in Fig. '1. Connected at one end with this arm '61 is a spring 68 the opposite end of which is connected to the housing As shown 1 there is-projecting outwardly fromthe dollar 65 a bracket to which is connected one end 01 an operating bar 69, this eene euontemg a pivotal one. As shown in Fig. 1 this 'operatingbar 69 is pivotally "connected at its upper end with the link H which is ifiiredly mounted at its op ;oosite end on thejpin .12 'to which "is fixedly mounted a handle'l3 whereby the p'iri'lZ may be rocked to effect the reciprd uen of the series.

Formed in'the shaitor axis"!!! and extending axially thereof are the spaced apart passages 1'4 and adapted forxcoimnunicating with the radially directedp'a'ssages "l6 and formed in the sleeve 44 as shown in Fig.4. e

Formed at the lo -atioh of the collard?!) through the shaft or axle in are the' -spaced apart pas-' sages 1'8 and 19,'the"p assage "f8 being adapted "for communication with the passage "15, the passage 14 being adapted for 'commimication with the passage'm as shown-mere. '1. Inali'gnment with the passage -89 formed fhroiigh 'the'tu'lde as shown in Fig, 3 is an eizhanstpa ssa'ge t'l. -Posihoned around the shaft in at the collar as, as shown in Fig. '3 are the -sealing gaskets 82' and 83;

Positioned in the "housi g is a partition embodying a strip of metal formed toprovide the plates .84 and havifig"the channel Boat their meetin point for receptio'ii of a sealing strip 81. Found in one of the sections, as shown in Fig. 2, at th location urine part tion members B4 and 85 is an opening In forming the structure, the members "84 and 85 are mounted in one of the sections so as to eiitend upwardly therefrom, these members "84 "and 85 being of the same width as thehous ing so that the opposite side edges or these members 84 and 85 engage the'botto'ms of the oppositely disposed cup-shaped members. H After tnese'meriibers' '8'4 and 85 are mounted in one of the ass sses-es members, the other is positioned over "it and the assembly shown in Fig. "3 is :adcempnsuea. In order to seal around the eases er the mem ers 84 and "8'5 at their nietilig'with'the'faoe df "the cup-Shaped i'nn'ifier pos'itiohed the'reover the opening 88 is provided and the assembler by inserting the hafld iii the open-mg 88 spray or otherwise 'depos'italong the meeting edges,

thus rock the collar 65 in one direction or the other. The tube 89 would of course be attached tea source of fluid and in the description we will assume that it is attached to the intake niani'fold so that there is a suction outwardly through the tube 89. Upon rocking the handle 13' so as to force the rod or bar 69 downwardly, the collar will be rocked to the right of Fig. 2, the degree of racking being "limited "by the pin 83 which is engaged in the slot '92. This rock" mew-111 be against the tension of the spring '68; When rocked in this position-as shown into Fig; 7, the passage '14 will be brought into commune cation with the passage 8'0 so that suction will beset up i'nthe passage "M arid this passage-14 would-communicate as shown in Fig; 4 through the passage '71 with the interior-of the housin at one side of the blade 'or vane B. Atthe same time, the passage 15 which communicates through the passage "IS with the interior-arise housing at the oppositeside of the blade 'l3, will be brought into communicationwith the passage 8| as shown in Fig. 7 thus opening the interior of the housing at one side of the blade-or vane B to the atmosphere arid establishing a partial vacutnn at the opposite side of the blade. will cause a rotation or the housing until the blade or vane B contacts either with the steps 90 or 9| which are punched inwardly from the faces or the housing section. As the housing rotates, it will rotate the gear '64 which is iii mesh with the teeth on the head .35 so as to rock thesegment bearing arm 34. This rocking may be effectedirom the position'sho'wnin Fig. 2 to the position shown in 'Fig. 1; depending upon whether or not-the operator desires the window to be entirely open. Immediately upon releasing the downward pressure on the handle 13, the spring 68 will serve to rock the collar baclrward-ly into normal or neutral position and thus the window will remain stationary at the selected point. Should the handle be rocked in the opposite direction, the collar would be swung so that the passage '8! would 'be in communication with the passage 19 thus establishing communication of the passage 14 with the atmosphere and at the same time, passage 18 would' be' brought into communicationwith the passagetfl thus establishing communication of the passage 15 with the source of vacuum, so that the movement of the housing would be in the opposite direction and the segment arm '34 would swing upwardly to the position shown in Fig.2 so as to close the window.

Experience has shown that at times thepower opera-ted mechanism may not operate "due to failure of the engine to function. In Fig. 8+w'e have illustrated a modification in which'the-attachment may be added to the structure --'so'that the window may be raised and lowered ihannally. Mounted on the plate 39d whioh corresponds with the plate 39 is a bushing 94 in which is positioned a sleeve '95 carrying a gear 96 which meshes with the gear "65 and --which im'ayjbe rotated by the crank 91. iigi- 9'wehavesaswaa misnerss at rhodification in which the collar is providedwith a fitting98 communicating with the passage 8I. On this fitting 98 is a conduit 99. If it is desired to use the structure for operation by means of hydraulics, the tube 99 serves as a means for carrying the exhaust through it to a properly located sump.

Fig. 10 we have shown a modification in which the blade or vane is stationary, as a movable'iho'using is connected direct to the actuating arm. In this view, the valve plug IOI, which may be rotated in any suitable manner, is provided with the axially directed passages I02 and I03: communicating by the lateral passes I04 and I05 with the outlets I06 and I01 formed in the hub I08 projecting outwardly from which is the vane or blade I0Ia provided with the sealing strip. I I0, at its end, to engage'the inner surface of the housing III. This housing is also providedwith the sealing strip II 2 toengage the member I08. The plug IOI may be rotated to the desired position and, when rotated, the housing will rotate around the vane I0'Ia which is stationary. Pivotally connected to this housing is the-actuating arm II3 which is pivotally connected at its opposite ends to the re-enforcin strip, II4 on the window H5. The general operation of this structure is substantially the same as already described.

Fig. 11 shows a further modification in which a stationary housing has a moving vane and the moving vane is geared directly to the segment arm. In this structure, the housing II! is provided with the solid portion IIB leading into which is a tube I I9 communicating with the cut away portion I2I of thevalve plug I20 which is provided with a similar bore I20a. A passage I22 is adapted to communicate with the recess I2I, as is likewise the passage I25. The passage I23 is adapted to communicate through the passage I 23a with the bore I20a. The passage I 24 is adapted to communicate with the recess -I2I. This plug I20 may be manually operated in any manner desired. The blade or vane I26 is adapted to move around the shaft I29'on which the hub I2! is mounted, this hub I21 carrying teeth I28 meshing with the teeth I39 on the head I30 of the segment arm I32 which is pivotally mounted to one end of the actuating rod or bar I 33. The opposite end of this actuating bar I33 is pivotally connected to the re-enforcing strip I34 of the window I35. It is believed that the operation of the device will be obvious with the drawing given in view of the description given above. By manually rotating the plug I20 the partial vacuum may be created at either side of the moving vane I23 and simultaneously the interior of the housing at the opposite side of the vane will be open to the atmosphere.

. In Fig. 12 we have shown a further modification in which a stationary housing is used with a movable vane and the shaft on which the vane is mounted. rotates in unison with it and is provided exterior of the housing with a connection for the actuating arm. As shown in Fig. 12, the

housing I36 is provided with an offset portion I31 formed in the interior I38 of which are passages I39, I40, MI and I43. Mounted in this block I38 ,is a valve plug I42 having its periphery cut away'atI44 for connecting either passage I39 or I431to a vacuum pipe I45. 'Axially mounted on a shaft .I46'projecting into thehous'ing is the jheadpI4I' of the vane arm. I49, there being a sealing'strip 'I48carried bythefmember I38 engaging the periphery of the hub I41. Fixedly mounted on the shaft I46 exterior of the housing is an arm I50 which is pivotally connected to one end of the actuating arm I5I the other end of which is pivotally connected to a re-enforcingstrip I52 of the Window I53. By rotating the valve plug I42, manually or in any other desired manner, passage I40 0r I4I may be alternately connected to theatmosphere while passage I43 or I39 is connected to vacuum so as to effect a rock-- ing of the shaft I46 and thus eifect a raising and lowering of the window. 9

Experience has shown that a window operating device constructed in this manner has proven highly efficient and that a fluid operated motor of this type is one which lends itself to various adaptations and uses because of its light-' ness, compactness, durability and high efiiciency in operation.
